CVE-2025-26793
Published: April 11, 2026
Official Description
The Web GUI configuration panel of Hirsch (formerly Identiv and Viscount) Enterphone MESH through 2024 ships with default credentials (username freedom, password viscount). The administrator is not prompted to change these credentials on initial configuration, and changing the credentials requires many steps. Attackers can use the credentials over the Internet via mesh.webadmin.MESHAdminServlet to gain access to dozens of Canadian and U.S. apartment buildings and obtain building residents' PII. NOTE: the Supplier's perspective is that the "vulnerable systems are not following manufacturers' recommendations to change the default password."
Technical Analysis
CVE-2025-26793 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-26793 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
